Renal Cell Carcinoma with Deep Vein Thrombosis / 대한비뇨기과학회지

The association between cancer and deep vein thrombosis or pulmonary embolism has been recognized by most clinicians. Adenocarcinoma of the pancreas, female reproductive organs, breast, colon, lung, and prostate have been found to be associated with the highest risk of deep vein thrombosis. However, the isolated deep vein thrombosis is a rare phenomenon in renal cell carcinoma. Only two cases of deep vein thrombosis in renal cell carcinoma were reported in the literature. The tumor thrombi of renal cell carcinoma is found in renal vein and inferior vena cava, with the incidence of 20-49% and 5-10%, respectively. We report two cases of renal cell carcinoma which are associated with the deep vein thrombosis due to the obstruction of inferior vena cava by the tumor thrombi.

The Value of Prostate Specific Antigen, Digital Rectal Examination, Transrectal Ultrasound, and Transrectal Ultrasound-Guided Biopsy in Prediction of Final Pathologic Diagnosis in Prostate Cancer / 대한비뇨기과학회지

PURPOSE: We evaluated the clinical utility of preoperative serum prostate specific antigen (PSA), digital rectal examination (DRE), transrectal ultrasound (TRUS), and findings of TRUS-guided biopsies in predicting the final pathologic diagnosis in patients who underwent radical prostatectomy. MATERIALS AND METHODS: The medical records of 53 patients with prostate cancer who underwent radical prostatectomy from september 1995 to June 2000 were reviewed. Pathologic variables evaluated on sextant biopsies included total length and percent of cancer on one core, number of cores involved and Gleason score. Clinical variables included PSA and PSA density (PSAD). Also subjects were divided into two groups; organ-confined group versus non organ-confined group. RESULTS: On final pathologic examination, 38 patients (72%) had organ-confined, 11 patients (21%) had margin positive, 6 patients (11%) had capsular penetration and 6 patients (11%) had seminal vesicle involvement. None had pelvic lymph node metastases. Chi-square analysis demonstrated significant correlations between PSA, PSAD, number of cores involved, total length of cancer on one core and organ-confined prostate cancer. When PSA level was 11 or more, PSAD was 0.34 or more, biopsies had Gleason scores of 7 or more, number of cores involved was two or more, and total length of cancer on one core was 0.4cm or more, possibility of cancer being non organ-confined increased CONCLUSIONS: This study demonstrates that PSA, PSAD, Gleason score in sextant biopsy, number of cores involved, total length of cancer on one core are clinically useful predictors of organ-confined disease. This may help both patients and clinician in selecting the most appropriate therapeutic approach.

A Case of Seminal Vesicle Cyst associated with Ipsilateral Ectopic Ureter and Renal Agenesis / 대한비뇨기과학회지

Seminal vesicle cysts combined with ipsilateral renal agenesis represent a rare urologic anomaly. This urogenital malformation is explained as a developmental failure in the same mesodermal region. We report a case of seminal vesicle cyst, ipsilateral dilated ureter and renal agenesis which was treated by surgical excision. And we searched the literature to review the clinical presentation, diagnosis and treatment options of this anomaly.
